Gateway 7811fx undervolting

I am currently trying to undervolt my gateway 7811 fx using the "Undervolting Guide" here on NR.

I was wondering if anyone knows the lowest values you can go for the laptop to run stable so I don't have to spend all that time looking for the best value.

Thanks

 

I recommend reading a bit more if you are still confused. It says in the guide many times processors are different and somewhat unique, you must test your own processor to find its lowest values. Copying someone else's values is like cheating on a test using someone elses answers, even though they had a different test.

It doesnt take that long, just allocate some time because stress testing is tedious.

The T9900 has many more multipliers than the P8400, you should be greatful you only have those few

 

you could just download CPUgenie (use the free 14 day trial) and get it to do the hard work for you; trouble is.....the shortest test time is around 30hours and the maximum test time is 60hours. It basically decreases the voltage to the CPU in small amounts and runs a stability test (of varying times depenging on selected test options) per multiplier.

Although I use CPUgenie, I didn't bother with the 30-60hour test straight off the bat. I manually lowered the voltage to my X9100 until it BSODed (takes 15mins max.); did a hard-reset; upped the voltage to the next highest voltage after the one that caused the BSOD; then let CPUgenie stress test my new voltage; double checked it with OCCT.

 

I tested the auto stress test....and its FAIL. the problem is, sometimes it BSODs, and then when the system restarts its defaults back to the original settings, and you have to start over. Did that on my 7811 4 times before I gave up.

I've also quit recommending CPUGenie, no questions get answered on their forums, and emails to tech support and their general email go unanswered.

Lastly, deleting CPUGenie completely from your system if you choose not to buy it is damned near impossible.

 

IIRC CPUgenie gives the user the option to either keep the previous settings or reset back to default config. When i encountered a BSOD during CPUgenie 30hour test, i simply selected keep exisiting voltages and it resumed from there.

Double checked with OCCT after @ suspected multiplier and altered voltage.

On the plus side, I have managed to complete the 30hour CPUgenie test without BSODing. It was only when i selected unlocked voltages and ran the test again that BSOD happened @ 11.0x multiplier on my X9100.
